Scanning probe microscopy techniques like STM and AFM facilitate the characterization of atoms and molecules on flat substrates with nearly unrivaled spatial resolution. Utilizing the strengths of these techniques, our team is looking to build custom molecular structures in a bottom-up manner and characterize their physical properties.
The main focus of this work is on endohedral fullerenes, a class of compounds that facilitate the stabilization of exotic configurations of few-atom structures within a carbon cage. Among them are some of the best single molecule magnets discovered to date, as well as promising candidates for spin-qubits. These desirable traits are combined with very high chemical stability. Utilizing the physical properties of these fascinating compounds is limited by two main issues: synthetic yield and, to a lesser degree, crystalline order. Both can be addressed elegantly by focusing on their properties in low dimensional arrangements, like monolayers or single molecules on ultraflat surfaces.
In this presentation we will detail our ongoing efforts of utilizing a broad range of deposition techniques, molecule manipulation on the surface, and chemical self-assembly approaches.
